This week on the DocTalk program, Kansas State University veterinarian Dan Thomson, DVM, MS, PhD, discusses pinkeye with his K-State colleague Matt Miesner DVM, MS, DACVIM. Miesner outlines how the pathogen Moraxella bovis is associated with pinkeye, but the infection typically occurs when exposure is accompanied by physical damage to the eye, from dust, forages, flies or other causes. He also discusses diagnostics, prevention and treatment options for pinkeye, one of the most economically damaging diseases in cattle. The DocTalk section on BovineVetOnline also houses archives of the program. Previous episodes include discussions of heat stress in cattle, preconditioning calves, parasite control, equine reproduction and low-stress livestock handling.
